For more effective utilization of individual
herd data, production benchmark values utilizing the NCBA-IRM-SPA calculations
were obtained from CHAPSTM herds with a total of 88,000 cows exposed to bulls and
processed during 2010-2014. CHAPSTM compares each individual producer's performance
against the benchmarks. Thebenchmark values for the NCBA-IRM-SPA traits are as
follows:
